Abstract
The utility model relates to a double-boiler barrel vertically arranged type natural ventilating waste heat boiler which comprises an upper boiler barrel, a lower boiler barrel, a convection bank, a meter valve, a boiler wall, a smoke gas inlet and a smoke gas outlet, wherein both sides of the front part and the back part of the upper boiler barrel and both sides of the front part and the back part of the lower boiler barrel are respectively provided with a descending pipe, the descending pipes are communicated with the upper boiler barrel and the lower boiler barrel, boiler tops on both sides of the upper boiler barrel are respectively provided with a row of movable boiler covers, and the convection bank is of in-line arrangement. The utility model has the advantages that because the waste heat boiler adopts natural ventilation, the waste heat boiler saves the dynamic force consumption of a draught fan, the in-line arrangement of the convection bank can effectively reduce the smoke gas resistance of the system, the descending pipes arranged on the utility model effectively improve the water circulation of the boiler and the boiler tops are provided with the movable boiler covers which can be opened in the process of the running of the boiler for carrying out thorough dust cleaning for the boiler.
Description
Technical field
The utility model relates to a kind of pair of drum longitudinal gravity-flow ventilation waste heat boiler, is applicable to the waste heat recovery of industries such as controlling gold, coking, is specially adapted to refine the magnesium industry.
Background technology
At present, control the waste heat boiler of gold, coking industry use, the general pair drum longitudinals that adopt, it includes upper and lower drum, convection bank, instrument valve, furnace wall, gas approach, exhanst gas outlet etc., and be equipped with air-introduced machine to carry out forced ventilation.Because the heat transfer of waste heat boiler mainly is to carry out in the mode of convection heat transfer' heat-transfer by convection, so the heating surface area of waste heat boiler is bigger, the air-introduced machine configuration is also bigger, thereby power consumption is also bigger.For the low capacity waste heat boiler, can adopt the gravity-flow ventilation form, thus the cancellation air-introduced machine.But when adopting gravity-flow ventilation, boiler heating surface need strengthen a lot, and the upper and lower drum of boiler must long enough, causes that the water circulation is bad easily like this, causes the semiconvection pipe to be out of shape.Simultaneously, after the employing gravity-flow ventilation, because flue gas flow rate must be enough low, self does not have self-cleaning action flue gas, and when dust content was big, the stifled ash of appearance influenced boiler output easily.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of water of putting boiler that can change and circulates, and is convenient to timely, thorough deashing to improve boiler heat-transfer effect and energy-conservation two drum longitudinal gravity-flow ventilation waste heat boilers.
The technical scheme that its technical problem that solves the utility model adopts:
The utility model includes upper drum, lower drum, convection bank, instrument valve, furnace wall, gas approach, exhanst gas outlet; Convection bank is connected with upper and lower drum, it is characterized in that being respectively equipped with a down-comer in the both sides of the front and rear of upper and lower drum, and down-comer is connected with upper and lower drum, and the caliber of down-comer is φ 108-159mm, and down-comer is arranged in furnace wall.
The utility model is respectively equipped with the movable bell of 1 row on the furnace roof of the both sides of upper drum, the bottom of each movable bell is the tetragonous cone table suitable with cleaning door.
Convection bank of the present utility model is to arrange along row.
The beneficial effects of the utility model are as follows: (1) this waste heat boiler has been cancelled air-introduced machine owing to adopt gravity-flow ventilation, has saved the air-introduced machine power consumption; (2) convection bank is to arrange along row, can effectively reduce system's flue gas resistance; (3) set down-comer has improved the water circulation of boiler effectively; (4) furnace roof is provided with movable bell, can open movable bell in boiler operatiopn boiler is carried out thorough deashing.
